Webb13 sep. 2011 · In the present analysis we evaluated the impact of MGMT-promother methylation as well as IDH1-mutational status on outcome in 160 patients with GBM treated with radiation and temozolomide. IDH1 mutations occur in approximately 60 - 80% of diffusely infiltrating gliomas of the WHO grades II and III and in secondary GBM but … Webb21 dec. 2012 · Methods. BTSCs were cultured from GBM patients and MGMT promoter methylation, and the mutation statuses of EGFR, PTEN, and TP53 were determined. Endogenous JAK2/STAT3 activity was assessed in human GBM tissue, BTSCs, and orthotopic xenografts by immunohistochemistry and Western blotting.
